QTCreator failed to build on Windows due to error C2509: 'createTestObjects': member function not declared in 'SilverSearcher::Internal::SilverSearcherPlugin'

I tried to build QTCreator (master branch, revision a45b0d2) with VS2015 Update 3 on Windows. It failed to build due to the error below:
D:\QTCreator\src\src\plugins\silversearcher\silversearcherplugin.cpp(48): error C2509: 'createTestObjects': member function not declared in 'SilverSearcher::Internal::SilverSearcherPlugin'

In silversearcherplugin.h file:
#ifdef WITH_TESTS
private:
QList<QObject *> createTestObjects() const override;
#endif

In silversearcherplugin.cpp file:
QList<QObject *> SilverSearcherPlugin::createTestObjects() const
{
return

{new OutputParserTest};
}

We should change the code in silversearcherplugin.cpp file as below. Then QTCreator can be built successfully.
#ifdef WITH_TESTS
QList<QObject *> SilverSearcherPlugin::createTestObjects() const
{
return {new OutputParserTest}

;
}
#endif

Could you take a look at this? Thanks!
